: :the county of Milwaukee and stateofis cousin, have-invented a new and useful.Dis-' 1 tended for 3 is an end elevation of the same.

.1. To all whom ihn'aj/ "comm 4 My invention'rel ates to concrete mixing machines for street paving, and the object 'of my improvement is to provide etlieient means for distributing the concrete, as it is of England,

No." 299 Fourte'enth" street; Milwaukee, in

tribnting S )out1 for flconcrete- Mixers' 'Inse in Street-PavinglVork, of which the followin is a'specification.-

received from the mixing machine,'-over the width of the street; thus dispensing with all wheeling and shovelin of the concrete. This purpose is aeeomplisied by'means of the device shown in the aecompanyingdrawings in which Figure l-is a side view of the device. Fig. 2 is a plan view of the same, and Fig.

In these drawings the mixing machine is not completely illustrated, as it forms no part of my present invention, except that the two machines necessarily cooperate.

The mixer shown is the same machine shown in my application #549,015, which relates to the same general subject matter, to-wit: a machine for street paving.

10 is the mixer drum, 11 the truck frame and 13 is the ring gear, by means of which the drum is driven.

14 is the discharge spout thron h which the concrete is delivered from he mixer drum to the distributing spout hop er 1!), whence it finds its way to the distributing spout 16. This spout 10 has internal blades 17, all set on an angle to the spout and inclined in the proper direction, according to the direction in which the spout is rotated, to move the concrete away from the'mixer and discharge it from the free end of the spout 10.

The spout is rotated from the mixer drum ring gear 13 through the pinion 17, shaft 18, sprocket, wheel 19, chain 20, miter gears 21, s iaft 22 and chain 23 engaging sprocket wheel 24 on the 8 out 16. The spout is supported from the oom 25, which is pivoted f R Q imi.QELWI QN N? ted Man 18,1 9 1 3.

.2; rod 27,.which'also swings ona vertical pivot Be it known that. I,- Enw \no WV. BRACK-- 'r.xauar, a subject of the Kin residing at and whose post-of ice address is at 28. The outer end of the spent 16 is supthat the inner end-is supported by chain .23, except that the latter not'only supports but drives the"spout, while the former, chain 20, runs idle. 'The spoutlt'v is steadied laterally and kept iuplace on the chains by two sets,;of"rollers 30 and 31 adjacent to the outer and inner chains respectively. The rollers are carried by the frames 32 and 33, which depend from the boom 25. The rollers engage in grooves 34in the hubs of the sprocket wheels. A hand rail 35 is provided for swinging the s out and boom so that the concrete may 0 deposited anywhere within the sweep of the spout which is about 150 degrees. This hand rail is attached to the two do iendent frames 32 and 33.

At 36, ig. 1, a sliding jaw clutch is placed to be operated by lever 37. This clutch connects the shaft 18 and sprocket 19 when 0 eration of the spent 10 is desired. \Vhen t m clutch 30 is disengaged, the shaft 18 turns loosely in thesproeket 19. The spout ho iper 15 is supported from the boom 25 and (.lt31ClltlCllt1ltllllO 33 with its center in line with the vertical pivots 26 and 28, so that said hopper 15 always stands in operative relation to the discharge spout 14 regardless of how the boom may be swung. The spout is inclined slightly with its free end lower than its receiving end to facilitate discharge.

By removin the two castings that form the boxes for tie vertical pivots 2G and 28, the entire boom, distributing Sllt 1t), and all attached parts are removed tram the machine, leaving the mixer to be operated in the ordinary way.

\Vhat I claim as my invention is:

1. A distributing means for concrete mixers consisting of a rotatable substantially horizontal pipe conveyor, a frame pivoted at one end on a vertical shaft and adapted to swing horizontally, means rotatably supporting said eouvcyer from said frame, and a train of mechanism acting through the axis of said pivot shaft adapted to rotate said conveyor in any position of said pivoted frame.

2. A distributing means for concrete mixat 20 to swing horizontally. The free end of the boom is supported by the double tie ers consisting of a rotatable substantially isconsin,i'assleivos fr'oi'rsis1'1. L.

ported bythe chain 29 in the same manner horizontal pipe conveyer, a frame pivoted I its center line in the line of the axis of said in at one end on a vertical shaft and adaptpivot shaft. ed to swing horizontally, means rotatably In testimony whereof I have hereunto set supportin said conveyer from said frame, my hand and seal this 20th day of May 1910.

a train 0 mechanism actin throu h the r p 1 axis of said pivot shaft adigted to roiate PJDVVARD BRACI\LI\BURY said conveyer in any osition of said pivot- In the presence 0fed frame, and a feetfchute or hopper for E. O. S. NACKLETOW,

said conveyer mounted on said frame with H. H. Gammon.
